Circles Around The Sun

An author attempts to uncover who her older brother was before schizophrenia took hold of him in this “clear-eyed and heartbreaking” memoir (Publishers Weekly). Molly McClosky’s brother Mike was fourteen when she was born. So far apart in age, she barely knew him before schizophrenia took hold of him at the age of twenty-three. Within a few years, Mike’s world began to fall apart. By the time Molly was old enough to begin to know him, Mike was heavily medicated and frequently delusional, living in hospitals or care homes or on the road. Years later, through reading an astonishing archive of letters preserved by her mother and grandmother, and interviewing old friends of Mike's, Molly began to piece together a picture of her brother's life, before and after the illness struck—the story of how a gifted and well-liked student and athlete was overtaken by a terrible illness that rendered him unrecognizable. Now she tells that story, which is also the story of her own demons and of the ways in which a seemingly perfect family can slowly fall apart, and in the end, regroup.

In the third edition a number of minor misprints that appeared in the second edition have have been corrected. Furthermore, 17 new problems have been added, at the end of chapters 6, 8, 9, 11, 12, 13, and 14. The answers to these 17 problems have not been listed in the 'Answers' section at the end of the book. This will permit the problems to be used as hand-in problems or perhaps in mid-term exams. JMK €9 PGH Copenhagen May 2000 Preface to the Second Edition In the second edition, a number of misprints that appeared in the first edition have been corrected. In addition to this, we have made improvements based on the experience gathered in the use of the first English edition of the book in the introductory course in physics at the University of Copenhagen. A chapter introducing nonlinear dynamics has been added. The purpose of this chapter is to provide supplementary reading for the students who are interested in this area of active research, where Newtonian mechanics plays an essential role. The students who wish to dig deeper, should consult texts dedicated to the study of nonlinear dynamical systems and chaos. The literature list at the end of this book contains several references for the topic.

Has anyone ever seen with their own eyes that the Earth goes around the sun? Even to this day, no one has. However, 500 and even 2000 years ago, some astronomers managed to point out that this is the case. At that time, people’s range of activities was strictly confined, the technology and tools used were extremely primitive, and many of the mathematical methods used today had not been developed. How did those astronomers make and verify this discovery? This book explains this exciting demonstration process. It enables anyone with a basic junior-high-school knowledge of geometry and a certain degree of spatial imagination to understand this and other interesting discoveries in the solar system. By demonstrating this interesting process, the book not only satisfies readers' curiosity using the simplest mathematics, but also inspires them to explore the new and unknown world.

A lyrical recipe uses seasonal changes to explain to a child the time that passes between one birthday and the next. Includes a recipe for more traditional birthday cake, as well as information about the passage of time and how it is revealed through trees.

The three most basic shapes -- squares, triangles and circles -- are all around us, from the natural world to the one we've engineered. Full of fascinating facts about these shapes and their 3D counterparts, Shapes in Math, Science and Nature introduces young readers to the basics of geometry and reveals its applications at home, school and everywhere in between. Puzzles and activities add to the fun factor.

New to Penguin Classics, the astonishing story of the Copernican Revolution, told through the words of the ground-breaking scientists who brought it about In the late fifteenth century, it was believed that the earth stood motionless at the centre of a small, ordered cosmos. Just over two centuries later, everything had changed. Not only was the sun the centre of creation, but the entire practice of science had been revolutionised. This is the story of that astonishing transformation, told through the words of the astronomers and mathematicians at its heart. Bringing together excerpts from the works and letters of Copernicus, Galileo, Kepler, Descartes, Newton and others for the first time, The Dawn of Modern Cosmology is the definitive record of one of the great turning points in human history. Edited with Translations, Notes and an Introduction by Aviva Rothman

The book is dedicated to the role of visual representations in the history of early modern science. It brings together historical case studies from various fields and discusses epistemological questions such as the role of images as mediatory instances between practical and theoretical knowledge, the interaction between images and texts, and the potential of images to synthesize fragments of knowledge to a global picture.
